9VAC25-151-200. Sector M - Automobile salvage yards.

A. Discharges covered under this section. The requirements listed under this section apply to stormwater discharges associated with industrial activity from facilities engaged in dismantling or wrecking used motor vehicles for parts recycling or resale, and for scrap (SIC Code 5015).

B. Stormwater pollution prevention plan requirements. In addition to the requirements of Part III, the SWPPP shall include, at a minimum, the following items:

1. Site description.

a. Site map. The map shall include the location of each monitoring point, and an estimation (in acres) of the total area used for industrial activity including, but not limited to, dismantling, storage, and maintenance of used motor vehicle parts. The site map shall also identify where any of the following may be exposed to precipitation or surface runoff: vehicle storage areas; dismantling areas; parts storage areas (e.g., engine blocks, tires, hub caps, batteries, hoods, mufflers); and liquid storage tanks and drums for fuel and other fluids.

b. Summary of potential pollutant sources. The permittee shall assess the potential for the following activities to contribute pollutants to stormwater discharges: vehicle storage areas; dismantling areas; parts storage areas (e.g., engine blocks, tires, hub caps, batteries, and hoods); fueling stations.

2. Stormwater controls.

a. Spill and leak prevention procedures. All vehicles that are intended to be dismantled shall be properly drained of all fluids prior to being dismantled or crushed, or other equivalent means shall be taken to prevent leaks or spills of fluids.

b. Inspections. Upon arrival at the site, or as soon thereafter as feasible, vehicles shall be inspected for leaks. Any equipment containing oily parts, hydraulic fluids, any other types of fluids, or mercury switches shall be inspected at least quarterly (four times per year) for signs of leaks. All vessels and areas where hazardous materials and general automotive fluids are stored, including, but not limited to, mercury switches, brake fluid, transmission fluid, radiator water, and antifreeze, shall be inspected at least quarterly for leaks.

c. Employee training. Employee training shall, at a minimum, address the following areas when applicable to a facility: proper handling (collection, storage, and disposal) of oil, used mineral spirits, anti-freeze, mercury switches, and solvents.

d. Management of runoff. The permittee shall implement control measures to divert, infiltrate, reuse, contain, or otherwise reduce stormwater runoff to minimize pollutants in discharges from the facility. The following management practices shall be considered: berms or drainage ditches on the property line, to help prevent runon from neighboring properties; berms for uncovered outdoor storage of oily parts, engine blocks, and aboveground liquid storage; and the installation of detention ponds, filtering devices, and oil/water separators.

C. Benchmark monitoring and reporting requirements. Automobile salvage yards are required to monitor their stormwater discharges for the pollutants of concern listed in Table 200.
